RAL 100 45 25
Warm Verdigris
RAL 100 45 25 Warm Verdigris sits at hue 100, lightness 45, and chroma 25, a warm earthy mid-dark blue-green reminiscent of aged copper verdigris and coastal rock pools. It is specified for heritage structural elements, coastal interior millwork, and natural material colour coordination. The moderate chroma and darkness produce a colour that feels mineral, grounded, and connected to maritime landscapes.
